摘要
用工业棕榈油甲酯分别与单乙醇胺、二乙醇胺在氢氧化钾催化下合成棕榈基单乙醇酰胺和棕榈基二乙醇酰胺,其最高产率分别为92.2%和89.0%。与椰油基二乙醇酰胺相比,两者表面张力与乳化力性能相近,但棕榈基二乙醇酰胺泡沫性能较差。添加癸酸二乙醇酰胺可改善棕榈基二乙醇酰胺的泡沫性能,当n(癸酸二乙醇酰胺)∶n(棕榈基二乙醇酰胺)=1∶2.5复配时,泡沫高度提高1倍,与椰油基二乙醇酰胺的泡沫高度相当。
Palm methyl ester was employed to synthesize palmitoyl ethanolamide and palmitoyl diethanolamide in the presence of KOH. The optimum yield of palmitoyl ethanolamide and palmitoyl diethanolamide was 92.2% and 89.0%, respectively. The properties of palmitoyl diethanolamide and coconut diethanolamide were compared. The palmitoyl diethanolamide and coconut diethanolamide had similar surface tension and emulsifiability, while palmitoyl diethanolamide presented weaker foaming ability than coconut diethanolamide did. The addition of decanoyl diethanolamide could improve the foaming ability of palmitoyl diethanolamide; a mixture of decanoyl diethanolamide and palmitoyl diethanolamide with molar ratio 1：2.5 presented foaming ability similar to that of coconut diethanolamide ,which was twice as high as that of palmitoyl diethanolamide.
